Apache Spark reassigned SPARK-40151:
------------------------------------
Assignee: Apache Spark
> Fix return type for new median(interval) function
> --------------------------------------------------
>
> Key: SPARK-40151
> URL: https://issues.apache.org/jira/browse/SPARK-40151
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.4.0
> Reporter: Serge Rielau
> Assignee: Apache Spark
> Priority: Critical
>
> median() right now returns an interval of the same type as the input.
> We should instead match mean and avg():
> The result type is computed as for the arguments:
> - year-month interval: The result is an `INTERVAL YEAR TO MONTH`.
> - day-time interval: The result is an `INTERVAL DAY TO SECOND`.
> - In all other cases the result is a DOUBLE.
